Definitions

  • the invention relates to a device for transferring the rotational movement generated by a drive to a non-rotary stem of a shutoff valve.
  • a threaded sleeve which surrounds the stem is necessary in order to transfer the rotational motion of a drive to the stem.
  • the threaded sleeve in cast iron and steel valves is normally received by a machined hub.
  • the hub is carried by an attachment which is disposed on the valve housing and has the form of a yoke (KSB Armaturen-Handbuch, 1965).
  • an attachment constituted by a yoke can be employed only through the use of an expensive welded construction.
  • this conflicts with the requirement, imposed specifically on sheet metal valves, for easily manufactured individual components joined to one another by a few weld seams.
  • an attachment consisting of a rotationally symmetrical body and carrying the lower bearing location for the threaded sleeve, and a bearing cap connected to the attachment of a flange and containing the upper bearing location.
  • FIG. 1 shows a shutoff valve sectioned in the region of the stem drive
  • FIGS. 2 and 3 show enlarged individual views of the components forming the bearing locations for the stem drive of FIG. 1, and
  • FIGS. 4 and 5 show different embodiments of the bearing locations.
  • the shutoff valve illustrated in FIG. 1 has a sheet metal housing 1 which is closed off from the atmosphere by a cover secured by means of a flange 2.
  • An attachment 3 is disposed on and welded to the cover.
  • the attachment 3 has a flange 4 which serves as a connection to a bearing disc 5 resting on the attachment 3, and as a connection to a bearing cap 6.
  • the bearing disc 5 and bearing cap 6 embrace a threaded sleeve 7 which is connected to a handwheel 8.
  • An ascending, non-rotary stem 9 is surrounded by the threaded sleeve 7 which transfers a rotational movement generated by the handwheel 8 to the stem 9 in such a manner that the latter and a closure non-illustrated element--connected thereto are raised or lowered depending upon the direction of rotation.
  • the threaded sleeve 7 is supported by additional plain bearing elements 10 and 11 which are fixed to the threaded sleeve 7.
  • Such plain bearing elements can likewise be provided on the bearing disc 5 or the bearing cap 6. They can consist of individual members which may, for example, be adhesively connected to the component carrying them; they can also be formed by spraying an antifriction material onto one or both sliding components or can be loosely connected therewith.
  • the bearing disc 5 which in the exemplary embodiment of FIGS. 1 to 3 is provided with a recessed portion or a protuberance 12 serving for centering in the attachment 3, acts as an axial bearing during backward flow through the shutoff valve.
  • a sleeve-like upper region or a recessed portion of the bearing cap 6 assumes the axial bearing function during forward flow through the valve and the radial bearing function during flow in any direction.
  • a bearing collar is eliminated.
  • the axial bearing function during backward flow through the valve is here assumed by a ball bearing whose balls 13 are supported on a shoulder 15 provided in the attachment 14.
  • a bearing cap 16 acts as an axial bearing during forward flow through the valve, as well as a radial bearing, in the manner described above.
  • FIG. 5 has a bearing disc 17 and a bearing cap 18 which are likewise made of sheet metal.
  • Support is here provided by a ball bearing whose balls 19 are disposed in a circular corrugation 20 of the bearing disc 17 and in a compartment defined by the threaded sleeve 21 and the bearing cap 18.
